Additional information: "date of event" changed from: blank to: (b)(6) 2018.Removed statement "the date of the event is unknown".Removed unknown and in.Added product name.Added lot #, catalog #, serial #, and expiration date.Added manufacture date device evaluation: the product was returned with the membrane completely unfolded and blood found on the exterior of the catheter and between the catheter and the sheath.The extender tubing was also returned with the syringe attached.Small amount of clear fluid was observed inside the syringe.No clear fluid or blood was detected inside the iab catheter.Two kinks were found on the catheter tubing approximately 40.6cm and 40.9cm from the iab tip.The technician attempted to flush/aspirate the inner lumen and was unable to do so.The technician then attempted to insert a laboratory 0.018¿ guide wire through the inner lumen of the returned iab and found that the inner lumen was occluded.The technician was unable to clear the occlusion, however evidence of dried blood was observed at the tip of the guide wire.An underwater leak test of the balloon, catheter, y-fitting, extracorporeal and extender tubing was performed and no leaks were detected.The iab was placed on the cs300 pump and pumped for two hours which represents one complete auto fill cycle.The iab pumped normally and no alarm sounded from the pump.Alarm, iab catheter restriction & kink: the evaluation determined there was a kink in the catheter.It is difficult to determine when or how a kink in the catheter occurs.Although we did not repeat the event in the laboratory setting, a kink in the catheter can cause inflation difficulty or an alarm.We were unable to duplicate the reported alarm.However the evaluation confirmed the reported kink.Clotted iab: the evaluation confirmed the reported clotted iab.Blood clotting within the inner lumen will seal the passage.It is difficult to determine when the occlusion occurs, however, if this occurs during the procedure it will be impossible to flush or aspirate through the inner lumen.It can also cause poor or no pressure waveform and guide wire insertion difficulty.Clear fluid in iab: an evaluation of the product was unable to confirm the reported clear fluid in iab.A device and lot history record review was completed for the reported product.No non-conformances were found that are considered to be related to the event.Complaint # (b)(4), record # (b)(4).
